Across
  1. 4. negatively charge particles

  3. 6. a bare metal rod that is usually coded with chemical compounds called flux
  4. 7. joins metals, using a variety of techniques and processes
  5. 8. using the heat of an arc as a heat source.
  6. 11. the opposition to the flow of current and circuit
  7. 12. the bottom of the weld groove opposite the weld face
  8. 16. electrons flow and one direction

  10. 19. has two surfaces at right angles, and the bead is triangular in shape
  11. 21. something that allows the flow of electrons
Down

  7. 10. a welding process used to apply a hard, wear-resistant layer of metal to surfaces or edges of worn-out parts
  8. 13. the percentage of a 10 minute period in which a welder can operate at a given current setting
  9. 14. When electrical current alternates or reverses the direction of electron flow
  10. 15. the distance from the tip of the bear end of the electron to the base metal
  11. 18. a weld made in a groove between the two pieces of a metal to be joined
  12. 20. the direction in which the current is flowing
